viewpager通过自己写几个view设置viewpage

View viewOne = getItemCodeView(oneList);
            View viewTwo = getItemCodeView(twoList);
            ArrayList<View> viewList = new ArrayList<>();
            viewList.add(viewOne);
            viewList.add(viewTwo);
            vpCode.setAdapter(new CodeTypePageAdapter(viewList));
            vpCode.addOnPageChangeListener(this);

 private View getItemCodeView(ArrayList<Integer> list) {
        View view = LayoutInflater.from(this).inflate(R.layout.item_vp_code_type, vpCode, false);
        RecyclerView rv = (RecyclerView) view.findViewById(R.id.rv_code_type);
        rv.setLayoutManager(new GridLayoutManager(this, 4));
        CodeTypeAdapter codeTypeAdapter = new CodeTypeAdapter();
        rv.setAdapter(codeTypeAdapter);
        codeTypeAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(BaseQuickAdapter baseQuickAdapter, View view, int i) {
                startSendCode((int) baseQuickAdapter.getItem(i));
            }
        });
        codeTypeAdapter.setNewData(list);
        return view;
    }

public class CodeTypePageAdapter extends PagerAdapter {
    private ArrayList<View> list;

    public CodeTypePageAdapter(ArrayList<View> list) {
        this.list = list;
    }
    @Override
    public int getCount() {
        return list == null ? 0 : list.size();
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        View view = list.get(position);
        container.addView(list.get(position), ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        return view;
    }
    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        if (object == null)
            return;
        container.removeView((View) object);
    }
